Four new types of squeeze film dampers have been experimentally investigated to develop a practical and effective damper for flexible rotors. The cylindrical bush damper was selected as the best one among them and applied in a test rotor supported on ball bearings. A stable running of the rotor exceeding the critical speed was observed.
